1,072,515, Specification 'of Letters Patent. Patented Sept. 9, 1913. Application filed April 1, 1913. Serial N 0. 758,095.

resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Im rovements in Gas-Burner Valves and Lig liters, of which the following is a specification.

This invention relates to gas burning de-. vices, and particularly to those used to}: illuminating purposes.

In as jets, burners, stoves, etc, it hap= pens that the valve is accidentally or on knowingly opened, which causes escape of gas, and sometimes explosion and suffocation.

The principal object of my invention is to providesimple and improved means, op-

erated by the gas valve, for automatically lighting the gas without the use of matches, and for preventing the aforesaid accidents.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a general elevation of a gas jet and the improvements, and shows the position of the device when the valve is turned on and the gas burns. Fig. 2 is a side .view of Fig. 1. Fig. 3-is an elevation similar to Fig. 1, and shows the position of the device when the valve is closed and the light out.

A. gas-jet, such as usually employed for illumlnation, for which the invention is here shown as adapted, comprises the extremity of a gas pipe 1 leading from the-main, a cook or valve 2 for turning the gas on and ofi, a burner 8, and a gas tip4= for producing the proper flame. A tube 5 is secured adjacent the jet to a bracket 6 attached to the burner 3, and a steel abrading wheel 7 is rotatabl mounted at the upper extremity 5 or said tube by means of the wheel-shaft 8 running in bearings 9 of-ears 10 forming part of the tube. Within the upper part of .tube 5 is disposed a block ll'of sparking material, such as a cerium and iron alloy 01'; other suitable compound which will emit sparks when abraded by steel. A thumb screw 12 threads into the lower part of tube 5, and aspring 13 is located between the extremity of said screw and block 11, whereby it presses against the block and forces it to bear continually against the milled or toothed periphery of wheel 7, so that a sudden rotation of said wheel in a clockwise direction, as viewed in the drawing, will cause a shower of sparks to be emitteddirectly above the gas-tip 4. A v

Upon the shaft 8 is secured an arm 14- provided with a longitudinal slot 15, and to the end of the valve-barrel 16 is secureda lever 17. The opposite end of lever 17 'engages the arm .14, bym'eans of a pin 18 thereon fitting within the slot 15 and being provided with round heads 19 at each end to guide the arm and lever. Therefore, when the valve 2is turned by its thumb-wing 20 from its closed position in Fig. 3 to its .epen position in Fig. 1, the lever 17 is actuated and the arm 14 caused to swing in a clockwise direction from the position in Fig. 3 to that in Fig. 1, whereby the gas is turned on and said wheel is rotated to emit sparks and ignite the gas. When the valve is turned back and the gas shut off, said lever and arm are restored to the position shown in Fig. 3. In the open position of the valve the lever 17 and arm 14 are disposed away from the gas flame, as indicated by the dot and dash lines, Fig. 2, so that said parts do not interfere with the light.

It will be noted that block 11 being pressed by spring 18 against wheel 7 offers resistance to the swinging of lever 17 and arm 14 and consequently to theturning in either direction of valve 2. Said resistance is least when the arm 14 is at the commencement of its stroke, Fig. 3, due to the pin 18 being farthest from the wheel 7 and the leverage thereat greatest, and increases as the arm approaches its midway position, shown by the dot and dash lines, Fig. 3. At this point the leverage is shortest and resistance greatest, and asthe arm: 14. approaches the opposite end of its stroke, Fig. 1, said resistance diminishes steadily. This action brakes the valve 2, which commences to turn with ease, and when midway turns difiicultly, and then completes its stroke with an abrupt and sudden snap movement. The wheel 7 is thus rotated suddenly by the snap action of the valve, whereby it emits a large shower of sparks to light the gas when it is turned on. Said snap action making it comparatively difiicult to turn the wing 20 when the i cidents due to escape of gas arethereby pre- 1 10 j vented. Should however the valve be opened at any time, without intention, it

would cause the gas to light and thereby prevent its free escape and the consequent d The pin 18 abutting against the extremity of slot 15 prevents further rotation of the valve 2 When it is set to either of its positions.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

said lever and arm being actuated to light the gas when turned on by said valve.

2. The combination with a gas jet, and a valve therefor, of a tube adjacent said jet, an abrading wheel mounted on said tube, a springepressed sparking compound within said tube bearing against said wheel, a slotted arm fixed to said wheel, and a lever fulcrumed on said valve engaging the s 0t in said arm, said valve actuating said levei and arm to rotate said wheel for lighting the gas and to impart a snap movement thereto when opened and closed.
